Current Sampling

Introduction

API

group spinner_drivers_currsmp

Typedefs

typedef void (*currsmp_regulation_cb_t)(void *ctx)

Current sampling regulation callback.

Functions

static inline void currsmp_configure(const struct device *dev, currsmp_regulation_cb_t regulation_cb, void *ctx)

Configure current sampling device.

Note

This function needs to be called before calling currsmp_start().

Parameters:

  • dev – [in] Current sampling device.

  • regulation_cb – [in] Callback called on each regulation cycle.

  • ctx – [in] Callback context.

static inline void currsmp_get_currents(const struct device *dev, struct currsmp_curr *curr)

Get phase currents.

Parameters:

  • dev – [in] Current sampling device.

  • curr – [out] Pointer where phase currents will be stored.

static inline void currsmp_set_sector(const struct device *dev, uint8_t sector)

Set SV-PWM sector.

Parameters:

  • dev – [in] Current sampling device.

  • sector – [in] SV-PWM sector.

static inline uint32_t currsmp_get_smp_time(const struct device *dev)

Obtain currents sampling time in nanoseconds.

Parameters:

  • dev – [in] Current sampling device.

Returns:

Sampling time in nanoseconds (zero indicates error).

static inline void currsmp_start(const struct device *dev)

Start sampling currents.

See also

currsmp_stop()

Parameters:

  • dev – [in] Current sampling device.

static inline void currsmp_stop(const struct device *dev)

Stop sampling currents.

Parameters:

  • dev – [in] Current sampling device.

static inline void currsmp_pause(const struct device *dev)

Pause current sampling.

See also

currsmp_resume()

Note

This function can be used to prevent current sampling to call the regulation callback, thus allowing to adjust shared context.

Parameters:

  • dev – Current sampling device.

static inline void currsmp_resume(const struct device *dev)

Resume current sampling.

Parameters:

  • dev – Current sampling device.

struct currsmp_curr
#include <currsmp.h>

Current sampling currents.
